Do any of you charge a late fee for payments not received. I send a pre-addressed return envelope to all of my customers. Most pay immediately, but there are some who are almost a month late...every month. I don't want to drop these customers, because I have a tight/easy route. They eventually pay, but I get tired of financing things that come up such as their kids soccer camp. Now getting to my question, do any of you charge a $10 or 10% fee for checks not received by the 15th of the month.
